It's nearly complete. I plan to finish it over the Christmas and New Year quiet period. But proof reading by a German friend will take a month and printing and publishing will take up to two months, so the answer is in the Spring. (I laugh inwardly as I write this, because here in Yorkshire, England the ambient temperature is 60 degrees F and our daffodils are coming out; in other words Spring has already arrived, courtesy of global warming!) So April-May 2016.

Thank you Bob! I am so sorry for my late reply. I have been planning to make some pictures of the prop but I had to get it out of storage first and well, time went by. Thank you again for your reply, really dont want to be the guy who comes ask for information, then disappears.

2. And my database of British WW1 aircraft props, which runs to about 2000 lines of data.

If you have a British or German WW1 prop that you have not told me about (many of you have for which I am most grateful) or if you have any documents from the time which list propellers, please let me know.

With kind regards,

Bob

Dave; could you make this a sticky please.

Hello Bob, Does yor database include props made by S&S Aircraft in Winnipeg, Canada?
If not do you know who would?

Good morning from Ramstein Air Base, Germany! I have recently purchased a WWI German propeller...wondered if by chance you might be interested in including it in your database. Here’s the info from the hub:

Jntegral Propellor
N7982
D270 S145
100PS MERC6CYL

I believe this to be a prototype for the D I or D II, as my understanding is the production Mercedes engines had either 180 or 200 hp engines. Your thoughts? Here are a couple of photos...if you’re interested, I can get a better overall photo after the stand is ready.

Click the "Edit" button on the bottom of your post, scroll down, then follow the steps in the attachment to this page. If that doesn't work it's probably because the file is too large. If that's the case you can mail them to dbahnson "at" gmail.com and I'll process them for you.

Your prop is for a German aircraft designed early in WW1 and the serial number is also from early in WW1. I have recorded only one other with your dimensions and engine, 7504. It was succeeded by a prop with a slightly larger pitch, 1500 mm.

It probably dates from 1915 and was used on the LVG BIII, the Alb BII and the Alb Doppeldecker (which probably refers to the Alb BII).

The Mercedes engine for the Flying Troops began life around 1913 in four cylinder form producing 70hp which quickly became a six cylinder of 100ps, for which your prop was made. This was soon developed to produce 120ps.
